From solar cell origami lamps to cute nano-origami animals, we can’t get enough of the Japanese art of folding paper. The newest origami creations to catch our eye are Takayuki Hori’s beautiful folded figures, which feature 8 endangered species. Dubbed Oritsunagumono — things folded and connected — these X-ray origami works of art include a sea turtle, a waterfowl, and 6 other animals that are in danger of disappearing altogether.

Takayuki Hori’s folded Oritsunagumono figures feature the skeletons of eight endangered species delicately printed on translucent paper. A visual communication design graduate from Kanazawa College of Art, Hori tempers the art of origami with an environmental message. Delicate, crafty, beautiful and sad, these X-ray Origami art pieces remind us the importance of looking after these ephemeral endangered creatures.
